RELATED APPLICATIONS

This application claims the benefit of priority from U.S. Provisional Patent Application No. 62/026,155, filed Jul. 18, 2014, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

Various embodiments of the present disclosure relate generally to generating user interfaces. More specifically, particular embodiments of the present disclosure relate to systems and methods for generating a user interface from a data store.

BACKGROUND

Typically, creating new user interfaces for software applications or online publishing requires new source code to be written by software developers. In a software application, for example, a user interface would be designed, and a trained developer would write source code that renders user interface objects on a display and allows user interaction according to the intended functionality. In online publishing of web pages, when a web page is accessed, a user interface may be written in a static markup language or a dynamic language that renders markup language. In either case, source code is written that causes the user interface to be rendered and behave in the desired manner.

Writing source code is time consuming and expensive due to the need to use highly-skilled programmers. Updating source code is also a challenge, since the code can be lengthy and difficult for even skilled programmers to interpret.

DESCRIPTION OF THE EMBODIMENTS

While the present disclosure is described herein with reference to illustrative embodiments for particular applications, it should be understood that embodiments of the present disclosure are not limited thereto. Other embodiments are possible, and modifications can be made to the described embodiments within the spirit and scope of the teachings herein, as they may be applied to the above-noted field of the present disclosure or to any additional fields in which such embodiments would be of significant utility.

In view of the challenges associated with the conventional techniques outlined above, systems and methods are disclosed herein for processing and displaying user interface pages generated from a data store. Embodiments included herein may comprise a software application for creating and editing database records, although techniques herein would apply towards any application that uses graphical user interfaces, or interactive displays, also referred to as user interface pages.

In an embodiment, a privileged user may easily create, modify and delete user interface pages using at least one user interface page. User interfaces pages may further be created, modified and deleted by creating, modifying and deleting metadata in a data store, such as a database. User interfaces may be created, modified, and deleted, for example, in one or more maintenance pages displayed by the software application. Maintenance pages may provide the ability for an individual with minimal training to create complex, dynamic user interfaces that use rules and conditional logic. Further, such new interfaces may be created without the creation or generation of any new source code. Maintenance pages themselves may also be created, modified, or deleted using maintenance pages. As a result, metadata-generated pages may be created by user interfaces which are themselves metadata-generated. As a result, complex software applications may be developed and self-maintained by modifying a data store, without the involvement of highly trained software developers, and without requiring the creation or editing of source code, all of which saves substantial time and money.

In the detailed description herein, references to “one embodiment,” “an embodiment,” “an example embodiment,” etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to effect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.

Reference will now be made in detail to the exemplary embodiments of the disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

FIG. 1 is a schematic diagram of a network environment for generating user interface pages from a data store, according to an embodiment of the present disclosure. As shown in FIG. 1, the environment may include one or more users using user devices 102, which may be communicatively coupled to a server system 104 via an electronic network 100. One or more privileged user devices 106 may be used by privileged users in order to gain levels of additional access to one or more maintenance pages in a maintenance area 113, as discussed above. Electronic network 100 may include one or a combination of wired and/or wireless electronic networks. Network 100 may also include a local area network, a medium area network, or a wide area network, such as the Internet.

In one embodiment, each user device 102 and 106 may be any type of computing device configured to send and receive different types of content and data to and from various computing devices via network 100. Examples of such a computing device include, but are not limited to, a desktop computer or workstation, a laptop computer, a mobile handset, a personal digital assistant (PDA), a cellular telephone, a network appliance, a smart phone, or any combination of these or other types of computing devices having at least one processor, a local memory, a display (e.g., a monitor or touchscreen display), one or more user input devices, and a network communication interface. The user input device(s) may include any type or combination of input/output devices, such as a keyboard, touchpad, mouse, touchscreen, camera, and/or microphone.

In one embodiment, each of the user devices 102 and 106 may be configured to execute a software application 108, for example, via a web browser or browser installed for displaying various types of content and data received from any of server systems 104 via network 100. Server systems 104 in turn may be configured to receive user-generated content, e.g., in the form of data or metadata, from user devices 102 over electronic network 100. The data may be submitted by a user at each device 102 through an interface provided on a web page loaded within the browser executable at each device. Alternatively, application 108 may be accessed and executed locally, rather than via electronic network 100.

While user devices 102 and privileged user devices 106 are shown separately in FIG. 1, it should be noted that a single type of user device may be used by both regular users and privileged users. Further, while server system 104 is depicted as a single system or device, it should be noted that renderer 110, data store 115, maintenance area 113, and any other components described herein may be implemented using two or more server devices or systems. In an example, a single server 104 may be a web server that is configured to provide different versions of a web page and associated content to different user devices 102 and 106 according to user identity, the type of device, or type of web browser executable at the device, etc. The different versions of the web page may include, for example, a desktop version and a mobile version, for which the web page content may be formatted appropriately for display via the particular type of browser at the device. Further, any of the functionality of server system 104 may be operated by a single administrative entity, or outsourced to one or more other entities, such as a web hosting entity, web storage entity, and/or cloud computing service, possibly disposed remotely of each other.

Also, as shown in FIG. 1, server system 104 may include one or more data stores, such as databases 115. In an embodiment, data store 115 may be any type of data store or recording medium that may be used to store any type of data including, for example, user data, software application data, user display data, administration data, etc. While a single data store 115 is shown in FIG. 1, data and metadata may be stored across any number of data storage devices, including in cloud or remote storage devices. In an embodiment, renderer 110 may be configured to receive user input from one or more of user devices 102 and 106 and store the received input within data store 115. In some implementations, any received data may be stored in the data store 115 in an encrypted form to increase security of the data against unauthorized access.

As shown in the example of FIG. 1, application 108 may include a renderer 110. In an embodiment, renderer 110 may be configured to render user interface pages using data and metadata retrieved from at least one data store 115, where the user interface pages rendered may include maintenance pages associated with the maintenance area 113. Rendering system 110 may also be configured to process data from data store 115 based on metadata from data store 115 to create and display interactive user interface pages further based on rules and/or conditional logic, which may be user-determined. The rendering rules and/or conditional logic may be stored in metadata in the data store 115, allowing static and/or dynamic features of the application 108 to be added, updated, or deleted without modification of the source code, without compilation, and without requiring testing of the source code.

FIG. 2 illustrates an exemplary display user interface page 200 from application 108 displaying data from data store 115, according to an embodiment of the present disclosure. While FIG. 2 shows an example display page of a user application that may be created using the maintenance area 113 and renderer 110, it should be understood that any software application using graphical user interfaces may be generated with techniques presented herein. Display user interface page 200 may, for example, display a series of records 203 retrieved from a data store 115. Records 203 and/or other application data may be viewed and/or modified by privileged and/or unprivileged users. Rules and/or conditions stored in metadata from data store 115 may determine which records 203 and other user interface elements are displayed. More generally, metadata may at least partially determine the appearance and/or behavior and functionality of any user interface page in application 108. User interface pages of application 108 may be generated based upon the metadata. User interface elements displayed may also vary by date, time, user identity, and/or navigation path used to reach the display user interface page 200, etc., according to the rules and/or conditions stored in the metadata. Breadcrumb 205 may display the navigation path taken to reach the page. Filter fields 220 may be displayed according to rules and/or conditions, and may allow a user to narrow the records 203 displayed by selection of one or more filters. User interface buttons 210, and row edit links 215, may also be displayed according to rules and/or conditions contained in metadata. For example, row edit links 215 may be displayed only for users with sufficient access privileges.

Row edit links 215 may be selected by a user, which may cause the page to navigate to an edit user interface page, and/or additional user interface elements may be displayed. FIG. 3 illustrates an exemplary edit user interface page 300 for displaying content from a data store 115 associated with an individual database record. Users may modify record fields 305 in order to update or delete the record. Each record field 305 may be of a particular data type, which may be set in the metadata. Each record field may be rendered according to its data type, or may be set in metadata regardless of data type. For example, program name record field 310 may be set to be a drop down list, and thus a drop down arrow may be automatically rendered. Proposed start date record field 315 may be set to be a date field, and a date icon may be automatically rendered. Any and all user interface elements displayed may also vary by date, time, user identity, and/or navigation path used to reach the edit user interface page 300, etc., which may be set in metadata stored in data store 115. Additional record fields may be accessed for modification by selecting additional user interface buttons 307.

FIG. 4 is a flow diagram of an exemplary method for rendering a user interface page, such as the display user interface page 200 or the edit user interface page 300. At step 405, user privileges may be determined for the user interface page, which may affect which user interface elements are displayed and enabled. For example, create, retrieve, update, and delete capabilities may be enabled and rendered. At step 410, a menu may be created. At step 415, if data is to be inserted, at step 420, a database command such as an Structured Query Language (“SQL”) INSERT statement may be generated and executed. Data may also be updated at 425, in which case at 430, a database command such as an SQL UPDATE statement may be generated and executed. At step 435, a filter, such as filter fields 220, may be rendered based on data and/or metadata. At step 440, an SQL SELECT statement may be created and executed, which may return any number of data records from the data store 115 for display. At step 445, user privileges for user interface objects or elements such as titles, columns, buttons and links may be determined. User privileges may determine what user interface objects are displayed, and how they are displayed. At step 450, one or more user interface titles may be rendered. At step 455, one or more buttons may be rendered, such as at the top of the page 210.

If a display user interface page 200 is to be rendered, as may be determined at step 460, this rendering may be performed, as described, at step 465. Alternatively, if an edit user interface page 300 is to be rendered, this rendering may be performed, as described, at step 470. User interface pages 200 and 300 may have differing user interface elements to display, including additional buttons, as described at step 475. At step 480, any additional user interface elements such as buttons at the bottom of the page, may be rendered.

For the user interface elements rendered in FIG. 4, default or user-determined rules and/or conditional logic may be determined from metadata that affect which elements are displayed, and the manner in which they are displayed. While a particular order of rendering a user interface is shown in FIG. 4, namely top-down, the steps taken to render a user interface may be performed in nearly any order, including bottom-up, by element type, etc.

FIG. 5 illustrates an exemplary user interface page that acts as a maintenance page, according to an embodiment of the present disclosure. As discussed above, maintenance area 113 may be used to create, modify, and delete user interface pages and user interface elements. The maintenance area may be presented as single user interface page, or broken up into a plurality of interface pages, as shown in FIGS. 5-16. Maintenance page 500 may act as a maintenance home page, from which tables containing metadata used to render user interface pages of the application 108 may be viewed and modified. As a result, the appearance and/or functionality of one or more user interface pages in application 108 may be modified in the maintenance area 113 by modifying metadata, such as metadata stored in data store 115. Additional maintenance pages may be accessed if the user selects one of buttons 505, as will be discussed below in relation to FIGS. 6-16.

As discussed above, metadata stored in data store 115 may determine the appearance and behavior, including interactive behavior, of user interface pages of the application 108, including of the maintenance area 113. This metadata may be stored in tables of a relational database, for example, and may be modified by one or more users. Table name field 507 may display the name of the table currently being viewed in the maintenance page 500. As discussed above, the application may comprise display pages and edit pages. D Screen Title field 510 and E Screen Title field 515 allow a user to set the titles of the display and edit pages, respectively. At Insert on Screen field 520, as user may designate in a flag whether the users of the application will be able to insert new data on the display user interface page 200, or if the user will instead have to navigate to the edit user interface page 300. The Where Clause Text field 525 allows the user to designate filters applied to narrow the number of records displayed on display user interface page 200. The Order By Clause Text field 530 may allow a user to designate an order of fields by which records displayed on display user interface page 200 will be sorted.

The Additional Privilege SQL text field 535 may be a database request such as a SELECT statement, that dynamically gets privileges and determines which actions a user may perform on the user interface page. The display of the associated user interface page may also change based upon determined privileges. For example, “U” may indicate that a certain user has update privileges, and hence the ability to update the data being displayed on the page. Filter Query field 540 indicates whether the display user interface page 200 should automatically query when the user first opens the page. Filter Button Text field 545 may indicate the text to be displayed for the button, located near or on the filter fields 220, to limit the data displayed based on user-selected values in filter fields 220. Multiple Selection field 550 designates whether the user is able to select multiple filter criteria on the display user interface page 200. Row Tag Text 555 may identify one or more data fields in the row that will be evaluated to determine the format for the row of data displayed on the page. Row Tag Style Text 560 may indicate instructions, such as HTML instructions, that set the format or style for the row of data displayed on the page based on the row tag. As an example, Row Tag Text may be set to an “Amount” field, such that when the value of the Amount field is positive, the field and/or row displaying the value will be highlighted. Conversely, if the Amount field is negative, the field and/or row displaying the value will be highlighted in some other manner.

Row Style SQL text 565 indicates the format or style for the row data displayed on the page based on the execution of an SQL query. For example, the field may contain an SQL statement that references data displayed on the associated user interface page, any data that is accessible to the user in data store 115, and/or any information accessible within the data store 115 such as user privileges, date, etc. For example, the SQL statement “select ‘color:red” from dual” may cause the associated row in the user interface page to be indicated, such as by highlighting the row red. Other styles may be changed with the Row Style SQL text field, such as text color, highlight color, font style such as bold or italics, etc.

Row Style Text 570 indicates the format or style for the row of data displayed on the page. For example, the user may define a static background color for the row. Row Style Mod Number 575 indicates the number of the row(s) on which to apply the row styling on the page. For example, a “2” may indicate that a defined background color would be applied to every other row in the display user interface page 200.

The Perfunctory Display SQL Text field 591 may comprise a user-defined SQL SELECT statement that executes at the beginning of the rendering of the display user interface page 200 or edit user interface page 300. This SQL statement may set values for one or more variables to dynamically control the display and functionality of user interface objects to the user. For example, the SQL statement may set the value of Java variables referenced in one or more other fields for user interface objects, such as a column, button, link, filter, etc. For example, the code “select user from dual” may identify the specific user for which the user interface page is being displayed. The resulting value may then be used to determine the user interface objects that will be displayed to the user and, in addition, may be used control the behavior of those interface objects.

The Perfunctory Insert SQL Text field 593 may comprise a user-defined SQL SELECT statement that executes at the beginning of the rendering of the display user interface page 200 or edit user interface page 300. This SQL statement may set values for one or more variables to control the display of user interface objects to the user. For example, the SQL statement may execute one time and may set the value of Java variables referenced in one or more other fields for user interface objects such as a column, button, link, filter, etc. For example, the code “select round(<T_NUMBER/>) from dual” may round the value of a number field received from the user interface page to the nearest integer value (e.g. “4.6” would be rounded up to 5, etc.), and insert the resulting integer into the data store.

The Perfunctory Update SQL Text field 595 may comprise a user-defined SQL SELECT statement that executes at the beginning of the rendering of the edit user interface page 300. This SQL statement may set values for one or more variables to control the display of user interface objects to the user. For example, the SQL statement may set the value of Java variables referenced in one or more other fields for user interface objects such as a column, button, link, filter, etc. For example, the code “select round(<T_NUMBER/>) from dual” may round the value of a number field received from the data store to the nearest integer value (e.g. “4.6” would be rounded up to 5, etc.), and update the resulting integer in the data store.

As discussed in the Row Style Text 570 example above, static data such as background color may be used to render a user interface page. Dynamic conditions may also be inserted in fields to control the rendering of user interface elements. For example, the Row Style SQL text field 565 may be used to define dynamic SQL conditions which are determined at the time of the rendering of the user interface page. Conditions may be based upon the date, time, user identity, data values internal or external to the application, etc. For example, the user's identity may determine whether certain fields are displayed, or how they are displayed on the user interface page, based on the permissions associated with the user or type of user. The user interface page may even be rendered based upon a navigation path, such as the navigation path taken by the user in the application 108 to reach the maintenance area 113, or to reach the specific user interface page being displayed. Both static data and dynamic conditions may be stored in metadata in data store 115, and may be modified by an authorized user at any time. Further, static data and dynamic conditions may be based upon data and metadata associated with other user interface pages.

Break fields 580 through 589 in FIG. 5 may control the way data is grouped when being displayed to the user. These data groupings may be called “break groups.” Break group information may be applicable for any user interface display which displays more than one data record.

The Break Data Code field 580 may indicate whether displayed data is broken into groups by a column value (COL), or based on the number of rows of data (ROW). If the Break Data code field value is ROW, then the value for Break Data by Row Mod Number (Row Modulus Number) field 585 may determine the number of rows that are in each group. Further, if the Break Data Code field 580 is ROW, then the Break Data by Row Rem Number field 587 (Row Remaining Number) may determine the minimum number of rows of data that can be in each group. For example, the Break Data by Row Mod Number field 585 may be set to “7” and the Break Data by Row Rem Number field 587 may be set to “3”. If there are 20 rows of data to display on the user interface page, the 20 rows may be broken into 3 groups, 2 groups of 7 rows, and 1 group for the remaining 6 rows. Alternatively, if there were 23 rows of data, the rows will be broken into 3 groups, 2 groups of 7 rows and the last group 9 rows. Although the typical group max is 7 rows, a group of 9 may be allowed in this case because the overflow of 2 rows is less than the Break Data by Row Rem Number field value of 3.

If the Break Data Code field 580 is COL, information from the Flexible Column Screen may be used to create groups of data. All groups may be ordered alphabetically (for example, based on the column value(s)) and displayed on the user interface page.

The Break by Row HTML field 589 indicates the separator that is used between groups of data. This may be HTML text that creates a line between groups of data, although other types of dividers are possible. For example, the field value may be “<div style=‘border-bottom:dotted;’>”, which would create a dotted line along the bottom of each group.

Other dynamic fields may be included that impact the dynamic display of screen titles, the dynamic functionality of user interface pages, and the ordering of data displayed on user interface pages.

As discussed above, the maintenance page 500 may allow a user to modify a software module of the application 108, where the software module may be associated with a user interface page. This may include the ability to manipulate any software module, including the maintenance area 113 itself. Put another way, the maintenance area 113 may be self-modifiable. For example, a user may be able to set one or more variables, fields, rules, and/or conditions in order to control the rendering of the maintenance page 500. Thus, the maintenance page 500 may be used to dynamically modify the appearance of the maintenance page 500 itself. The maintenance page 500 may also modify multiple user interface pages simultaneously, such as, for example, the maintenance page 500 itself, and simultaneously one or more other user interface pages in the application 108. Upon modification, the maintenance page 500 may dynamically refresh to reflect the one or more modifications.

As discussed above, the maintenance area 113 may comprise a single user interface page, or a series of user interface pages. Other user interface pages in the maintenance area, such as those shown in FIGS. 6-16, may be accessible by buttons 505. FIG. 6 illustrates an exemplary user interface page 600 which allows modification of filter fields 220, according to an embodiment of the present disclosure. Any number of filter fields may be designated, and the contents and appearance of filter fields may be modified, for example, by selecting edit link 610 for the corresponding filter field record 605.

The edit link 610 may direct a user to the associated filter detail display 700, as shown in FIG. 7. In the filter detail display 700, a user may be able to modify a variety of attributes of a given filter field, for example, a filter field from the filter fields 220. The user may also define dynamic conditions, such as in SQL, regarding the population of a filter drop down list box, at Filter Ddlb SQL Text 705.

FIGS. 8a and 8b illustrate exemplary user interface pages that function as a flexible title maintenance display and edit, according to an embodiment of the present disclosure. Fields 805 in FIG. 8a list titles for various user interface pages in the application 108. If the user selects a title, the edit title page shown in FIG. 8b may be displayed. The edit title page allows a user to designate fields, such as the page associated with the title object 810, the print order 815, and dynamic rules and conditions associated with the display of the title 820.

FIG. 9 illustrates an exemplary user interface page that functions as a flexible button maintenance user interface 900, according to an embodiment of the present disclosure. The display may list button records 905 associated with one or more user interfaces of the application 108. A user may select to edit an individual button record, whereupon the page will redirect to the edit flexible button maintenance page 1000, as shown in FIG. 10. Fields in the edit flexible button maintenance page 1000 allow a user to designate the display order, screen placement, breadcrumb order, default display parameters, links, and privileges of buttons associated with various user interface pages of the application 108. For example, Button Link Text 1005 may indicate the link to be followed for the button displayed on the user interface page. Button Link SQL text 1007 may include a code snippet, such as SQL, that is executed in order to dynamically determine the button's link or universal resource locator (“URL”), which may incorporate conditions or rules. Button Procedure Text 1010 may indicate a method or procedure name to be called when the button is selected, while JavaScript Text 1013 may list JavaScript or other scripting language commands to be executed when the button is selected.

User interface designation, column text, display parameters, etc. may all be indicated by a user in order to configure the appearance and/or behavior of each column in the user interface pages of the application 108.

FIGS. 15a and 15b illustrate exemplary user interface pages 1500 that function as flexible layout table maintenance display pages, according to an embodiment of the present disclosure. Layout table records, as listed in FIG. 15a , may designate rules and conditions for the display of layout tables in application 108. If a user selects a layout table record, the page may navigate to the user interface page depicted in FIG. 15b , showing an edit flexible layout page. From the edit flexible layout page, the display order of layout tables, the maximum number of rows and columns, and other static and/or dynamic styling rules may be determined.

FIG. 16 illustrates an exemplary user interface page that functions as a lookup data type code maintenance display page 1600, according to an embodiment of the present disclosure. The application 108 may contain many data types, and fields of differing data types may be rendered in differing manners. For example, date fields may contain a selectable calendar emblem, while a flag field may include a check box. Lookup data type code maintenance display page 1600 may allow a user to create, edit and/or delete data types used in the application 108.

FIG. 17 is a schematic diagram of a data storage environment that allows the generation of user interface pages. If a user, such as a privileged user, wishes to create an application 108, at step 1705, the user may insert metadata into Maintenance Page Metadata 1710. As maintenance pages may not yet exist, the user may interact with the data store 115 using commands such as SQL commands. Once sufficient metadata has been provided by the user, at step 1715 the renderer 110 may automatically render and display one or more maintenance pages to the user. The renderer 110 may retrieve metadata from the Maintenance Page Metadata 1710 in the data store for this purpose. The user may then proceed to either step 1720 or step 1725. At step 1720, the user may continue to create, update, and/or delete metadata that affects the appearance and functionality of the one or more maintenance pages. At step 1725, the user may utilize the one or more maintenance pages to create, update, and/or delete metadata stored in the User Page Metadata 1730. User Page Metadata 1730 may be used by the renderer 110 at step 1735 to create, and determine the appearance and functionality of, user interface pages associated with the application 108. If the user interface pages of application 108 maintain associated user data, the user interface pages may maintain Application User Data 1740 in the data store 115.

FIG. 18 is a flow diagram of an exemplary method for generating user interface pages from a data store. At step 1805, at least a portion of metadata from a data store may be received, wherein the appearance of a plurality of user interface pages is based on the metadata. At step 1810, a display of a maintenance page based on at least a portion of the metadata may be generated, wherein the maintenance page is one of the plurality of user interface pages, and wherein the maintenance page maintains the plurality of user interface pages. At step 1815, one or more instructions from the maintenance page may be received. At step 1820, the metadata based upon the one or more instructions may be updated. At step 1825, the appearance and functionality of the user interface and/or maintenance page may be modified based on the metadata.

One benefit of database-driven application generation techniques described herein is that the number of lines of source code that must be maintained for an application are reduced. Since user interfaces and application functionality may be modified without changing source code, software development life cycles may be compressed, allowing newer versions of the software to reach a production environment more quickly. Further, changes may be made to an application without requiring the use of highly trained software developers. Instead, privileged users with sufficient permissions may make changes to the application in a graphical user interface in real-time, and see the changes reflected in the production environment immediately or nearly immediately. Since the amount of source code associated with each software application is reduced, testing is typically faster and may be accomplished more easily. This helps reduce application maintenance costs. Further, application changes can be made entirely using database modifications, rather than source code changes. Since the source code is unchanging, the source code itself does not need debugging or tested when modifications are made. Changes made in the maintenance area may also propagate to a plurality of user interface pages

Using techniques presented herein, application 108 may be used to generate a user-defined application system, including a navigational menu, user privileges, and interactive user interface pages. A large range of maintenance functionality may also be provided, such as the ability to view, insert, update, delete, etc., user-maintained data.
